Eh, you really didn’t answer my question. There’s a reason law enforcement looks at motive as an early factor in an investigation. Usually where there’s no motive there’s no action.Fauci lied about masks because of fear the hospitals would run out of PPE. He lied about the vaccine level because he didn't think the American people could handle the truth about the level of vaccination needed to reach herd immunity, and because no one knew how effective the vaccines would be. If the vaccines were say That's not his role. He's not an elected official.
And although this article leads with Rubio's criticism (cause tweetstorms are cool I guess), it's the substance of the article that's important. Polling somehow is science? Really? Ultimately, Fauci made the choice to undermine his own credibility. Why should anyone believe him?
What motive does Fauci have to “undermine himself”. What does he gain? We aren’t talking something big here either we are talking an estimated moving target that he moved what, 10%...based on new information? His change in temperature about masking up is easily explainable and had everything to do with availability of PPE for front line healthcare workers. Whether that’s the right strategy or not is certainly a matter of opinion, but it’s not hard to wrap your head around that reasoning.
You provided an example which cited Rubio as calling Fauci a liar. What credibility does Rubio have? He mocked the virus early and often, and was first in line to get vaccinated. He has zero credibility. FWIW I would have voted for Rubio. I considered him the best of all candidates in the primary’s. His motive for getting this message out is pretty clear and is all about gathering support for his political future.
